Testing, Measurement and Maintenance Services

This service covers three work items: periodic measurement, fault detection and preventive maintenance.

≥ 1 MΩ Insulation Resistance Reference
≤ 1 Ω Earthing Resistance Target
ΔT > 15°C Thermal Scan Critical Threshold

Periodic measurements

Earthing resistance, insulation resistance and circuit continuity measurements are repeated at set intervals. Compared against past records, early warning signs such as a value drifting down over time become visible.

When an unexpected fault occurs, the field team locates the fault point with measurement instruments; for cable faults, a time-domain reflectometer (TDR) calculates the distance without any digging.

Test TypeApplication AreaRecommended Interval
Earthing Resistance MeasurementSubstation, MV/LV panelOnce a year
Insulation Resistance MeasurementCable, motor, panelOnce a year
Thermal Camera ScanningPanel under load1-2 times a year
Transformer Oil AnalysisPower transformerOnce a year

A gradual decline in insulation resistance over the years allows a maintenance decision to be made before a fault ever occurs.

  • Circuit continuity measurement

Standards We Apply

TS EN 61557 Electrical safety testing equipment
TS EN 50522 Earthing installations
IEC 60255 Protection relay and measurement

Frequently Asked Questions

How often should periodic measurements be done?
It depends on the facility type and regulatory requirements; earthing and insulation measurements are generally recommended once a year.
Can a thermal camera scan be done without stopping production?
Yes, the scan is carried out under load and doesn't affect the production flow.
Does fault detection involve digging?
The fault distance is calculated first using methods like TDR, and digging is only done at the confirmed point.
What format are measurement reports delivered in?
They're delivered as a digital PDF report, with a comparison table against past measurements added on request.
What data does transformer oil analysis include?
The report covers dissolved gas analysis, moisture content and dielectric strength values.
